Use this skill when a cluster of GitHub issues and pull requests has been reported for a common failure mode (Slack, iMessage, support threads, or manual list), and you need an evidence-based dedupe recommendation or execution.
Provide a consistent, evidence-driven triage pass for issue and PR clusters so duplicate work is folded, contributor credit is preserved, and cleanup actions stay auditable.
Execution is command-led and conservative: drive decisions from gh readbacks plus deterministic file/metadata checks only, and avoid speculative local analysis beyond triage logic.
